Novel mildew-resistant asphalt paint and preparation method thereof

Abstract

The invention relates to the technical field of building materials, and especially relates to a novel mildew-resistant asphalt paint and a preparation method thereof. The novel mildew-resistant asphalt paint is prepared from, by weight, 30-40 parts of a coal tar asphalt liquid, 15-25 parts of epoxy resin, 7-12 parts of zinc chromate, 20-25 parts of polyurethane, 10-15 parts of ethylene glycol, 1-3 parts of potassium chloride, 2-5 parts of sodium dodecyl benzene sulfonate, 8-11 parts of polyether acrylate, 2-6 parts of tetraethylammonium chloride, 2-7 parts of mica powder, 5-10 parts of an antiseptic, 3-7 parts of deionized water, 5-12 parts of aluminum powder, 3-5 parts of iron red, 1-6 parts of zinc yellow, 2-6 parts of ammonium bromide, 10-15 parts of tetraethylenepentamine, 2-5 parts of glycerol triacetate and 15-25 parts of xylene. The mildew-resistant asphalt paint with the advantages of simplicity in preparation, low cost, high and low temperature resistance, ageing resistance and good durability is prepared through adopting the coal tar asphalt liquid, polyurethane, epoxy resin and polyether acrylate and optimizing proportions of all the components, and the preparation method has the advantages of optimization of various technological parameters in the preparation process, increase of the production efficiency, and shortening of the preparation period.

Description

Technical field [0001] The invention relates to the technical field of building materials, in particular to a novel anti-mildew asphalt paint and a preparation method thereof. Background technique [0002] Asphalt paint is composed of coal tar pitch and coal tar as main raw materials, and organic solvents such as thinners, modifiers, and driers are added. The ratio of the main raw materials is generally different due to different climate, temperature, and use environment, and the use of modifiers is added according to different needs. [0003] Asphalt paint is suitable for the protection of steel structures, electrochemical railway systems, ships, bridges and all kinds of galvanized equipment, iron pipes, corrugated plates, and galvanized steel frame structures that are prone to corrosive environments such as high temperature, chemical, air pollution and high seaside salt. Coatings; in various fields, coatings are widely used, such as exterior walls, industrial warehouses, chemica...

AI Technical Summary

Problems solved by technology

[0003] Asphalt paint is suitable for the protection of steel structures, electrified railway systems, ships, bridges and various galvanized equipment, iron pipes, corrugated plates, and galvanized steel frame structures in high-temperature, chemical, air pollution, and seaside high-salt environments that are prone to corrosion. Coatings: In various fields, coatings are widely used, such as exterior walls, industrial warehouses, chemical, petroleum, food industry storage tanks and pipeline surfaces, factories, modern farms, freezers, private houses, office buildings and other buildings High-quality, traditionally organic solvent coatings, which are highly polluting and have defects such as poor heat resistance, long drying time, and poor corrosion resistance
